```
public abstract class SolrParams
extends Object
implements Serializable, MapWriter, Iterable<Map.Entry<String,String[]>>
```
SolrParams is designed to hold parameters to Solr, often from the request coming into Solr. It's basically a MultiMap of String keys to one or more String values. Neither keys nor values may be null. Unlike a general Map/MultiMap, the size is unknown without iterating over each parameter name.
